Vapour barrier installation in Thorburn, sealed before the board goes on

A vapour barrier is one of the few things in a build that is completely hidden and completely unforgiving — once the drywall is on, a torn sheet or an unsealed outlet box stays that way for the life of the wall. In Thorburn we install and seal 6 mil poly over the insulation on the warm side, lapped at the seams and sealed at every penetration, before any board goes up. Thorburn is an established Airdrie community where reno, repair and ceiling drywall are common, so basement development and the occasional upgrade where older insulation has settled or thinned are common here. We cover Thorburn and all of Airdrie, 7 days a week.

What affects the cost of vapour barrier installation in Thorburn?

Area, penetrations and detailing

Vapour barrier cost in Thorburn depends on the wall and ceiling area being covered, the number of penetrations that need sealing — outlets, vents, pipes and light boxes — and how much detail work the rim joist and window returns need. We measure the space and give a fixed price before we start.

Usually priced with the insulation

Most Thorburn vapour barrier work is quoted together with the insulation and the boarding that follows it, because it is the same crew and the same visit. Where Thorburn still has stipple, we check how many coats are on it before deciding to match or remove.

Which side the vapour barrier goes on, and why that is not optional

The warm side, always

In Thorburn the barrier goes on the warm side of the insulation — the side facing into the heated Thorburn room. That is what stops indoor moisture from travelling into the wall cavity and condensing when it reaches cold framing.

What goes wrong when it is reversed

A barrier installed on the cold side traps moisture inside the assembly instead of keeping it out. It is one of the few mistakes in a Thorburn wall that cannot be corrected without opening the wall back up, which is exactly why we check every Thorburn job before anything is covered.

How we install and seal it in Thorburn

Hung, lapped and sealed

We run the poly in the largest sheets the space allows to keep seams to a minimum, lap every seam over a stud or joist rather than in open cavity, and seal it — a stapled overlap on its own is not a seal.

The penetrations are the job

Outlet and switch boxes, bath fans, dryer vents, plumbing stacks and pot lights each get sealed individually in your Thorburn home. Poly on the walls with open boxes behind it is not a working vapour barrier, and it is the single most common thing we find on jobs that were started by someone else. Where Thorburn still has stipple, we check how many coats are on it before deciding to match or remove.

Why Thorburn homeowners have us do the vapour barrier

We are the ones boarding over it

As a drywall company we install the barrier the way we want to board over it, because we are the trade that has to live with what is behind the sheet in Thorburn.

Left ready to be looked at

We leave the barrier complete and visible so it can be inspected before the drywall goes on — nothing gets covered until it has been seen.

Fixed price, same-day reply

How Thorburn homes affect the work

Housing in Thorburn is mixed enough that two jobs on the same street can need completely different vapour barrier installation work.

Stipple ceilings turn up throughout Thorburn, often with more than one layer from earlier repairs, and each layer changes how the new work has to be feathered.

Popcorn ceilings are still in place in parts of Thorburn. Anything from that era is treated as unknown until its age is established, and handled accordingly.

Vapour Barrier Thorburn: your questions answered

Does my basement development in Thorburn need a vapour barrier?
Almost always, yes — exterior basement walls in our climate need a barrier on the warm side of the insulation before drywall. We confirm what your specific assembly needs on the site visit rather than guessing from the plan.
Which side of the insulation does the poly go on in a Thorburn home?
The warm side — the side facing into the heated room. It is the detail that gets reversed most often, and it is not correctable once the wall is boarded.
Do you seal the outlet boxes and vents in Thorburn?
Yes — every outlet, switch box, vent and pipe penetration gets sealed individually. Poly hung over open boxes looks finished and does not work.
Do I still need a vapour barrier in Thorburn if I have spray foam?
Sometimes not — some spray foam assemblies act as their own barrier, and adding poly over them can be the wrong call. It depends on the product and the thickness, so we confirm on site instead of assuming.
Can you do the vapour barrier and the drywall together in Thorburn?
Yes — insulation, vapour barrier and boarding as one job is the most common way we do it, and it means one crew is responsible for what ends up behind the wall. We also cover Bayside, Kings Heights, Coopers Crossing and the Airdrie area.
Do you provide free quotes in Thorburn?
Yes — we come out to your Thorburn home, look at the work and give you a real, fixed on-site price. No guessing after.
